Ultra Grand Slam Sport Fishing Charters and Captain Magnus Nilsson invite you down to Key West for an adventure of a lifetime. The company specializes in inshore, offshore, wrecks, and reef fishing trips that are great for seasoned enthusiasts and record-seekers alike.
Captain Magnus loves catching fish and having a great time on the water. The first mate will cater to your every need. We customize our trips to maximize your pleasure.
Whether you want to watch your friend reeling in the biggest catch in their life or you wish to test your angling skills and make a great catch possible, there is a trip for you. You will be able to enjoy the view, spot any action going on beneath the surface, and take in all the beauty of the surrounding waters from a flybridge.
Your day out will take you fishing for anything from Mutton Snapper and Kingfish to Black Grouper, Barracuda, Amberjack, Sharks, and Marlin. You will be trolling and live bait fishing for all big game species. Even if the weather doesn't cooperate, Capt. Magnus and his crew will take you to the sheltered waters, where you will be able to try your hand at Jacks, Shark, and Barracuda.
The 'Ultra Grand Slam' is a Concord AMF Brunswick with 47' of excellence. She has been uphauled in 2018 and comes powered by a pair of 450 HP Cummins engines. The Ultra Grand Slam is rigged with latest electronics, technologies, and professional accessories.
All trips come with the use of high-quality Penn International and Shimano tackle, as well as lures. Live bait will be caught on the trip.

Unbelievable experience. The guys worked hard to catch great fish. Snagged barracuda and king fish. Took fillets downtown to local restaurants for catch and cook that were unreal.

We had a great trip. Amazing crew.

Thank you Aaron, looking forward to next time.
The charter operator canceled 1 days prior to the trip date. This is an automated posting.
We had a great time and caught a lot of Dolphin. The captain and first mate were awsome . If you want the best boat and crew this is it no need to look any further.

Thank you Michael, it was indeed great fishing with you guys
